Thickness Design for Cement-Treated Base Pavements

Cement-treated base (CTB) pavements are widely utilized by Illinois local road agencies. The CTB lift may include existing hot-mix asphalt surface, old bituminous surface treatments, aggregate base/subbase, and subgrade soil. The process is typically labeled “full-depth reclamation.” The objective of the project is to develop (in cooperation with the Illinois Department of Transportation) a CTB thickness design procedure and supporting policies. Project activities will focus on falling weight deflectometer testing (per Illinois Department of Transportation) and further performance surveillance of projects considered in previous projects and the additional CTB projects identified by Illinois Department of Transportation and the project's principal investigator.
